No one replied to this.
I'd like to get this in to 0.9.4 and I have a simple question:
How do I post a message to the status bar so that it displays to the
user IMMEDIATELY?
Here's the stack at the time I need to post the message:

USER32! 77e71268()
In nsPluginHostImpl::SetUpPluginInstance()
{
//...
result = plugin->CreateInstance(NULL, kIPluginInstanceIID, (void **)&instance);
//...
}
This call to CreateInstance is where the big "freeze for at least 15
seconds" hit happens. I'd like to put something like:
aOwner->ShowStatus("Starting java...");
before the call to CreateInstance(), but when I do this, of course it
doesn't display, because we're ultimately executing on the WindowProc.
Is there any way to force the event loop to be processed?
Thanks,
Ed
